Plug connector for a star quad cable

Abstract

A plug connector for a cable having at least two signal conductors, in particular a star quad cable, having a signal conductor part and an insulating part which holds the signal conductor part. The signal conductor part has a spring lug, electrically and mechanically connected to a signal conductor, wherein the insulating part has an axial hole and a spring lug passes through each of said axial holes, wherein the holes are arranged to hold the spring lugs at a physical distance from one another. The spring lugs project beyond the insulating part at the plugging-side end and are bent over in such a way that the respective bent-over portions of the spring lugs run from the plugging-side end in the direction of the cable-side end on an outer face of the insulating part and can be resiliently elastically deformed in the radial direction.

1. A plug connector for a cable including at least two signal conductors, said plug connector comprising a signal conductor part and an insulating part which holds the signal conductor part, wherein the plug connector has a plugging-side end for plug-connection to a complementary plug connector, and a cable-side end for electrical and mechanical connection to the cable, wherein the signal conductor part for each signal conductor includes a spring lug electrically and mechanically connected to a signal conductor, wherein the insulating part for each spring lug includes an axial hole through which a spring lug passes, wherein the holes hold the spring lugs at a physical distance from one another, this distance corresponding to the distance between the signal conductors in the cable, the spring lugs formed such that they are longer than the insulating part in the axial direction, and project beyond the insulating part at the plugging-side end and bent over such that the bent-over portions of the spring lugs run from the plugging-side end in the direction of the cable-side end and on an outer face of the insulating part can be resiliently elastically deformed in the radial direction. 
     
     
       2. The plug connector of  claim 1 , including a number of grooves on the insulating part outer face running in the axial direction corresponding to the number of spring lugs, wherein the grooves are arranged and formed such that in each case a bent-over portion of a spring lug is arranged in one of the grooves. 
     
     
       3. The plug connector of  claim 1 , wherein the holes in the insulating part hold the spring lugs in a spatial position which corresponds to the arrangement of the signal conductors relative to one another in the cable. 
     
     
       4. The plug connector of  claim 1 , wherein the spring lugs are crimped onto ends of the signal conductors of the cable. 
     
     
       5. The plug connector of  claim 1 , including a supporting sleeve which grips the cable at the cable-side end of the plug connector. 
     
     
       6. The plug connector according to  claim 5 , wherein the supporting sleeve is crimped onto the cable. 
     
     
       7. A plug connector arrangement comprising a plug connector and a complementary mating plug connector, wherein the plug connector is formed in accordance with  claim 1  and the mating plug connector includes a number of contact elements corresponding to the number of spring lugs, such that the mating plug connector includes an insulating part in the form of a socket, the inner face of which is formed in a complementary manner to the outer face of the insulating part of the plug connector, the insulating part of the plug connector adapted for plugging axially into the socket of the mating plug connector, wherein the contact elements on the inner face of the socket of the mating plug connector are arranged in such a way that when the plug connector and mating plug connector are plugged together, each contact element of the mating plug connector is in electrical contact with a spring lug of the plug connector. 
     
     
       8. The connector arrangement of  claim 7 , wherein on its outer face the insulating part of the plug connector includes a number of grooves running in the axial direction corresponding to the number of spring lugs, the grooves receiving a bent-over portion of a spring lug, wherein the socket of the mating plug connector has radial ridges on its inner face which are arranged and formed in such a way that when the plug connector and mating plug connector are plugged together axially, each radial ridge engages in a groove on the outer face of the insulating part of the plug connector, wherein a contact element of the mating plug connector is arranged on each ridge of the socket. 
     
     
       9. The plug connector arrangement of  claim 8 , wherein the radial ridges of the socket of the mating plug connector are formed by the contact elements, arranged in grooves on the inner face of the socket of the mating plug connector. 
     
     
       10. The plug connector of  claim 2 , wherein the holes in the insulating part hold the spring lugs in a spatial position which corresponds to the arrangement of the signal conductors relative to one another in the cable. 
     
     
       11. The plug connector of  claim 3 , wherein the spring lugs are crimped onto ends of the signal conductors of the cable.
